Your product here is yourself, so prove that you are passionate about what you do, and detail the ways you can help them. Displaying testimonials is a huge selling point for this business. Give potential customers an inside look at one of the programs you offer so they know precisely what they will receive. Clearly state the prices for each service. Make sure to include contact information and encourage any questions they may have.
Starting a website can be a great way to build some side income in a fairly passive manner. Start a blog if you have interesting, unique, and informative stuff to tell your readers. You can then make money on advertising or having people pay for educational products or tools you produce. Or create a website that brings together buyers and sellers of a niche product from which you can charge a subscription or transaction fee. The key is to think outside the box and come up with an idea that can provide a unique solution for people. And even if you want to produce a website that is similar to ones already out there, do it bigger and better and find a way to differentiate yourself!
I created an “Every Day I’m Hustling” shirt and sold enough for the campaign to ship, but didn’t earn much on the experiment because of some not-very-effective Facebook advertising. Still, some opportunity here and a friend of mine is doing REALLY well with this. If you can create awesome designs and reach the right people with good Facebook targeting, Teespring can be very profitable.
